Okay, it's decided: os.urandom() must be changed for 3.5.2 to

One way to not block is to raise an exception. Since this is such
a rare occurrence anyway I don't see this being a problem, plus it
keeps everybody mostly happy: normal users won't see it hang,
crypto-folk won't see vulnerable-from-this-cause-by-default
machines, and those running Python early in the boot sequence will
have something they can figure out, plus an existing knob to work
around it [hashseed, I think?].<br>

Nope, I want the old behavior back. os.urandom() should read
/dev/random if getrandom() would block. As the British say, "it
should do what it says on the tin".<br>
